COLUMN-RULE.

Specification of Letters Patent.

Patented Sept. 1, 1914.

To all whom it may concern Be it known that I, GEORGE T. TRUNDLE,

Jr., a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Column-Rules, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a very simple, easily applied and eiiect-ive column ruling device for use on a segmental, drum-like holder having parallel longitudinal rails. Such a holder, for example, is illus ated by the drum of a Multigiaph where e rails have undercutchannels and are adapted to loosely confine parallel lines of; type grooved on their opposite sides.

My ruling device is well adapted for mounting on the Multigraph drumbetween type thereon, and itis so made that it may be (put in place after the type is on the drum, an when in place, is held against-dropping out oft-he drum byits coaction with the rails'and against longitudinal shifting 0n the drum by abutting the type held thereon. My rule comprises a thin flexible arcual strip havin on its inner edge radially pro .jecting teet which lie in. the same plane the successive teeth to pass into the channels.

' When in place the rule stands normalt'o the drum,that is, in the plane of a circular section and it retains itself thereon by rea son of the fact that it extends for a great enough are so that teeth (all projecting toward the center) converge across the heads of the rails, preventing the rule dropping out. The flexibility of the rule is an (S5112-- tial characteristic, us. with ut :uu-h llexihilit it. is impossilillc to put llll rule in plumlmtwccn typo already on the drum: lhul is to say, an inflexible rule ha ng; l1: uhl i edged radial teeth either could not he put I on the drum from the outside, or. it put on I which. have grooves 31 on their opposite acteristic that my rule may be put in place 1 from the sid of the drum of g impor:

the drum, would not hold itself s u dropping oti. as the drum rotates. T

tance, as it avoids the necessity of sliding the rule in endwise as the form is bein made up. Rules which underhang therails and slide in cndwise may be effective to print, but trouble and delay is encountered in making corrections inthe form set up. Furthermore, there is considerable delay in setting u p each column of type and takin a proof of it before a rule is put in place. rules the whole form 18 set up as usual without the rules and then the type matter is separated at the desired arcual line for a short distance and the rule lS.,W3.I ed into place. Then the type are shovev snugly against the rule or rules and'locl zed with clips in the usual manner and an effective printing form is provided. Another valuable characteristic of my rule isthat, because of its thinness and absence of any lateral flanges, the type may be set snugly against it, thus avoidin any waste of space between the type matter and the ruled lines in the printed form.

My invention is hereinafter more fully described and its essential characteristics are. set out in the claims. r

In the drawings, Figure 1 is a side elevation of one of my rules, the broken lines in this figure illustrating the radial character of the teeth; Fig. 2 is a perspective view of a por Vllith my tion of a Multigraph drum showin .some I of .my rules mounted thereon and s-owing one rule in the process of being put in place.

The thickness of the rule is exaggerated in this figure for clearness of perspective illustration; Fig. 3 is an enlarged cross section of the rifle held between adjacent type on an overhanging rail, such as employed in the Multigraph drum Fig.- 4 is a similar view showing two rules spaced by a spreader vto print adjacent parallel lines; Fig. 5 is a f diagrammatic elevation illustrating the retary character of the drum.

As illustrated in Fig.5, the drum or segment with its type may be a rotary. structure mounted on a shaft 15, and coacting with a roller platen 16, thus constitutin a rotary printing couple, as usual in the l\ ultigraph.

'30, in each of the figures, indicates my column rule.- This isa thin flexible arcu'al strip lying in a circular plane and having projecting radially from its inn'er'edge teeth 31. I obtain perfectly satisfactory results by makin the edges of these teeth perfectly radial, wliich is the most'convenient form of manufacture.. It should be noted, however, that the variation of any particular teeth from a arallel edged tooth is very slight. Accordingly, the teeth may be described as radialtee'th' havingv parallel edges. I r

The body portion of my rule is substansubstantially tially the same height as the heads of the type, so that, when inplace the rule stands on edge on the surface of the drum or seg ment and its outer edge is in substantially as the print- Owing to the comrinting edge of the rule e, where a soft platen is ing face of thetype.

employed, to raise an inch more or less above theQfa-ce of the type to give an absolutely unifoi hi impres' :sion, but. this-is ;a"refinement"w V hieh, may be ignored. .Tlie*";ei1cumferential',""distance across the teeth ofethei rulefis only slightly less than'thedistarice betweenthe rail heads. Accordinglypita veuld impossible .to shove such a'rul'e offanyconsiderabl e length by a straightdine moginent fihto .phsition from the side of the 1 mg, but experience demonstratcs that it is' 'a very'simple matter to successively warp the rule, allowing one.-

tooth after another to enter its Channel. As the rule comes into the upright position the radial direction of the teeth causes the edges thereof to enga e the substantially radial faces ofthejrail eads,-which holds .the rule effectively from drum as lt IOl'/2tS;- v My rule may .conveniently bemade ofordinary sheet brass, which is-hard enough so that kinks do not form in the rule during its flexure.

As heretofore stated, the rules shown in Fig. 2 are somewhat exaggerated in the thickness to enable them to be clearly shown The thickness honxever, ya

in perspective. rics with the Width of ther'iiii which it is desired to print. may be very thin apdsprint a very thin line, or. it may beflsoinewhat thicker to print a heavyJine. To print two adjacent parallel lines it is convenient to mount two thin its face athbiisandth of dropping off of the -"tyj eholder between the type thereon and That is to say, the rule rules side by side but separated by a. spacer made similar to'a rule but not of printing height. Such spacer is shown at 82 in Fig. '1 and its radial teeth are indicated at I have referred to-the rule being held in place against lateral shifting on thedrum by the abutting type, and this is a vefy convenient arrangement where it is desired to print type matter separated by column lines. For printing blanlrfornis, however,the rules may be held against lateral shifting by quads, which are locked in place, or-by spring clips occupying the channels and directly abutting the rules. Two of such clips are shown by way of illustration at 40, in

Fig. 2, and may be considered as constructed in accordance with Patent-No. 1,041,447.
